Who is getting the rest of the undergrad science degrees if Asians, Blacks, and Whites only account for 74% of them?
it distinguishes between white (59.3), Asian (10.8), Black or African American (3.9), Hispanic or Latino (10.4), American Indian or Alaska Native (0.3) Native Hawaiian or Other Pacific Islander (0.1) and Temporary visa holder (9.3) for Engineering
Edit: and More than one race, unknown, or other (5.9), adds up to 100
Similarly to we Britons speaking of 'Europe' and particularly 'Europeans' with the 'continental' implied - and even that phrase not really making sense, not meaning the same as 'mainland'!
Many modern forms just say ‘check any that apply’, so you can check both white and Asian, for example.
